The use of the differential geometry of a Riemannian space in the mathematical formulation of physical theories led to important developments in the geometry of such spaces. The concept of parallelism of vectors, as introduced by Levi-Civita, gave rise to a theory of the affine properties of a Riemannian space. Covariant differentiation, as developed by Christoffel and Ricci, is a fundamental process in this theory. Various writers, notably Eddington, Einstein and Weyl, in their efforts to formulate a combined theory of gravitation and electromagnetism, proposed a simultaneous generalization o.

This book presents two plays, both of which are translated into English for the first time. In Voyage to the Sonorous Land, or The Art of Asking, a cockeyed optimist and a spoilsport lead a group of characters to the hinterland of their imaginations, where they search not for the right answers but for the questions. The Hour We Knew Nothing of Each Other takes place in a city square where more than four hundred characters pass by one another without speaking a single word.

Despite the rapidly expanding ambit of physical research and the continual appearance of new branches of physics, the main thrust in its development was and is the attempt at a theoretical synthesis of the entire body of physical knowledge. The main triumphs in physical science were, as a rule, associ ated with the various phases of this synthesis. The most radical expression of this tendency is the program of construction of a unified physical theory. After Maxwellian electrodynamics had unified the phenomena of electricity, magnetism, and optics in a single theoretical scheme on the basis of the con cept of the electromagnetic field, the hope arose that the field concept would become the precise foundation of a new unified theory of the physical world. The limitations of an electromagnetic-field conception of physics, however, already had become clear in the first decade of the 20th century. The concept of a classical field was developed significantly in the general theory of relativity, which arose in the elaboration of a relativistic theory of gravitation. It was found that the gravitational field possesses, in addition to the properties inherent in the electromagnetic field, the important feature that it expresses the metric structure of the space-time continuum. This resulted in the following generalization of the program of a field synthesis of physics: The unified field representing gravitation and electromagnetism must also describe the geometry of space-time.

The first edition of Ernst Kurth’s Musikpsychologie appeared in 1931, and was regarded by contemporaneous psychologists as no less than the foundation for a new systematic approach to the perception and cognition of music. Time has hardly diminished Kurth’s standing as an original scholar with a distinctive point of view. Music theorists, both in Europe and North America, regard him as an important figure in the history of music theory. Daphne Tan and Christoph Neidhöfer’s first full translation provides English-speaking theorists the opportunity to delve deeper into his ideas. Indeed, Kurth’s concerns – listening habits and habituation, metaphorical language, the limits of memory, and the role of the body in music experience, to name a few – are shared by many in the field today, especially scholars who work at the intersections of music theory, psychology, linguistics, and related disciplines. And while Kurth’s approach lacks the scientific rigour of modern-day empirical musicology, Musikpsychologie nevertheless presents a source of testable hypotheses for those working in the area of music perception and cognition. This translation of Musikpsychologie also has the potential to inspire a new generation of composers, especially through the topics in the second section (energy, force, space, and matter) and, given the inherently interdisciplinary nature of this book and the number of philosophical and scientific sources Kurth incorporates, it will appeal to those interested in the history of science and particularly in the emergence of psychology as an academic discipline in the early 20th century.

On a business trip to Tunisia, Preising, a leading Swiss industrialist, is invited to spend the week with the daughter of a local gangster. He accompanies her to the wedding of two London city traders at a desert luxury resort that was once the site of an old Berber oasis. With the wedding party in full swing and the bride riding up the aisle on a camel, no one is aware that the global financial system stands on the brink of collapse. As the wedding guests nurse their hangovers, they learn that the British pound has depreciated tenfold, and their world begins to crumble around them. So begins Barbarian Spring, the debut novel from Jonas Lüscher, a major emerging voice in European fiction. The timely and unusual novel centers on a culture clash between high finance and the value system of the Maghreb. Provocative and entertaining, Barbarian Spring is a refreshingly original and all-too-believable satire for our times.

This collection of essays is intended as a tribute to Josef Maria Jauch on his sixtieth birthd~. Through his scientific work Jauch has justly earned an honored name in the community of theo retical physicists. Through his teaching and a long line of dis tinguished collaborators he has put an imprint on modern mathema tical physics. A number of Jauch's scientific collaborators, friends and admirers have contributed to this collection, and these essays reflect to some extent Jauch's own wide interests in the vast do main of theoretical physics. Josef Maria Jauch was born on 20 September 1914, the son of Josef Alois and Emma (nee Conti) Jauch, in Lucerne, Switzerland. Love of science was aroused in him early in his youth. At the age of twelve he came upon a popular book on astronomy, and an exam ple treated in this book mystified him. It was stated that if a planet travels around a centre of Newtonian attraction with a pe riod T, and if that planet were stopped and left to fall into the centre from any point of the circular orbit, it would arrive at the centre in the time T/I32. Young Josef puzzled about this for several months until he made his first scientific discovery : that this result could be derived from Kepler's third law in a quite elementary way.
